List all subdirectories on given level

Question

I have backup directory structure like this (all directories are not empty):

/home/backups/mysql/
    2012/
        12/
           15/
    2013/
        04/
         


        

Answer 1

You can use glob to search down a directory tree, like this:

import os, glob
def get_all_backup_paths(dir, level):
   pattern = dir + level * '/*'
   return [d for d in glob.glob(pattern) if os.path.isdir(d)]

I included a check for directories as well, in case there might be files mixed in with the directories.
